Describe the problem/error/question
I am just starting my N8N journey and but am getting confused and frustrated because I am unable to connect any of my preferred chat models. I tried AWS Bedrock first and saw that there was an error currently and would not be fixed anytime soon. So I moved to Google Gemini. The Chat model says connected but when I try to send a query through an error pops up.
What is the error message (if any)?
[GoogleGenerativeAI Error]: Failed to parse stream
